As shown on the drawings:

The improved collapsible and convertible article of furniture embodyingthis invention is of the combination bed and chair type, normallyadapted when not in use to be carried in collapsed form within a suitcase or carrier along with other articles of collapsible furniture, suchas chairs, as illustrated in Figure 2, which discloses a convertibletype of suit case or carrier consisting of two integrally connectedsections I and 2. The suit ease or carrier is of the convertible type,whereby the suit case may be opened up and used as a table or the likeof the type illustrated and claimed in my co-pending application forpatent entitled Table and carrying case, filed on even date herewith,Serial No. 238,998.

Each of the case or carrier sections I and 2 has mounted therein a pairof collapsible legs 3 which are normally folded within the case sectionsl and 2, as illustrated in Figure 2. The collapsible and portable typeof combination bed and chair embodying the present invention is normallyadapted to be collapsed in compact separate sections, as illustrated inFigures 4 and 8, permitting the same to be placed side by side incollapsed form within a section of the suit case, as illustrated inFigure 2, to occupy a comparatively small amount of space, to permit thebed to be stored away when not in use and also permitting the collapsedbed to be transported.

The improved combination bed and chair consists of two units adaptedwhen in collapsed form to be entirely separated from one another andfurthermore adapted to be interlocked with one another to form a jointarticle of collapsible furniture. The base or supporting unit of thearticle of furniture comprises a pair of side rails or bars 4constructed of wood or other suitable material. Each of the side rails 4has secured on each end thereof, by means of a screw 5 or the like, ametal end casting comprising a side or outer wall 6, a top flange 1, abottom flange 8, and an end wall 9. Integrally formed on the outer faceof the lower corner of the side plate 6 on each of the castings is a legstop or abutment lug I0. The side wall 6 on each of the castings isprovided with a leg bolt opening and a leg bolt slot I I. The bottomflange 8 of each of the castings is provided with a guide slot I2(Figure 6) Also provided on the side wall 6 of each of the castings isan inverted T-slot I3 (Figure 3), the shank end of which projectsupwardly and opens through the top flange 'I to communicate with a slotor notch I4.

Provided in the top and bottom anges 'I and 8 of each of the cornercastings of the base unit are bolt openings. Integrally formed on theinner surface of each of the casting top flanges 'I is a boss I5,positioned to project into a recess or notch provided on the top surfacenear each end of the side rails 4 to assist in preventing the side railsfrom being pulled out of the corner castings.

Integrally supported against the outer face of the side plate 6 of eachof the corner castings by means of a supporting bolt I6, is a base legI'I, which when in vertically supporting position contacts the stop I0to limit the swing of the leg. To prevent the leg I1 from swinging backto a closed position away from the stop I0, each of the corner castingshas slidably engaged therein a transversely projecting lock bolt I8adapted to slide outwardly through the slot Il. Integrally formed on thebottom edge of each of the locking bolts I8 is a downwardly projectingextension or nger I 9 which projects downwardly through the guide slotI2 in the bottom flange 8, thereby providing an arrangement for limitingthe shifting of the lock bolt I 8. To assist in holding the lock. boltin position, a spring-controlled pin or stud 2) is mountedin each end ofthe side rails 4 (as clearly illustrated in Figure 7). When the lockbolt I8 is projected outwardly, as illustrated in Figure 6, a base leg II is engaged between the stop I0 and the bolt I8 to prevent pivotalswinging of the leg in either direction.

Engaged through the bolt openings of the corner casting top and bottomflanges TI and 8 respectively is a bolt 2l. Pivotally supported on eachof the bolts 2l within the corner casting is one end of an end bracerail or transverse member 22 constructed of wood or other suitablematerial. The opposite end of each of the transverse or end brace rails22 is pivotally connected by means of a hinge 23 to the inner end ofanother end brace rail or member 22, the outer end of which is pivotallyconnected by means of a bolt 2l to an opposite corner casting. The twohingedly connected transverse brace rails 22 are arranged in pairs ateach end of the base unit and form transverse braces for holding theside rails properly spaced apart when the base unit is set up, asillustrated in Figure 5.

For the purpose of preventing the hingedly connected transverse braces22 from accidentally collapsing, each of the brace rails 22 is providedwith a recess 24 in which a gravity controlled latch bar 25 is pivotallysupported at one end by means of a pivot pin or bolt 26, as illustartedin Figure 7. The opposite end of the pivoted latch bar or bolt 25 hasone corner thereof notched as at 2l, forming a contact or stop pin 28adapted to drop into contact with the inner face of the bottom flange 8of a corner casting when the brace rail 22 is in bracing position atsubstantially right angles to the side rail 4. The notch 2'I in thelatch bolt 25 permits the latch bolt to drop over the inner edge of theflange 8 to position the latch bolt 25 in an inclined position, as shownin Figure '7, to act as a brace preventing the accidental collapsing ofthe hingedly connected brace rails 22.

To brace the lower end of the leg II against spreading outwardly awayfrom the side of the base section when the same is set up for use, thelower endsA of the two legs at each end of the base unit are connectedby means of a flexible brace strap 29 constructed of leather, canvas,belting or other suitable material and having the ends thereof bentaround the lower portions of the legs l'I and secured thereto by meansof nails or other suitable fastening devices. It will thus be seen thatthe combination article of furniture includes a base or supporting unit,as illustrated in Figures 4 to 7, inclusive, adapted normally to becollapsed and folded into a compact form, as illustrated in Figure 4, tostore the same in a comparatively small amount of space or to pack thesame into a suit case, as illustrated in Figure 2. The base unit may bereadily opened up for use by rst swinging the supporting legs I'Idownwardly from the positions illustrated in Figure 4 at right angles tothe side rails 4 and against the stop members I0, after which theshiftable latch bolts I8 are moved from the dotted linepositions shownin Figure`6 into thewfull `line positions, to hold the supporting legsl1 properly braced against accidental collapsing.

After the legs l1 have been dropped into supporting position, the twoside rails 4 are moved apart to their full amount, thereby causing thehingedly connected transverse brace rails 22 to swing to the full linepositions illustrated in Figure, so that the two brace rails 22 at eachend of the base unit are in substantial alignnient with one another. Inthe open position of the two transverse brace rails, thegravity-controlled latch bolts or bars 25 are adapted to drop downwardlyinto the full line position illustrated in Figure '1 to engage thebottom flanges 3 of the respective corner castings to hold the .hingedlyconnected transverse brace rails 22 against accidental collapsing. Withthe transverse brace rails in extended position, as illustrated inFigure 5, the ilexible brace straps 29 are opened up into full positionfor use and are held stretched across the iront and rear ends of the4base unit to brace the lower portions of the legs complete theassemblage.

Referring now to Figures 8 to 12, inclusive, which illustrate in detailthe various features of the top or bed section, consisting of a mattressunit constructed oi a strip oi canvas or other similar strong material.The mattress strip comprises a wide middle or intermediate main or seatsection 3U, a head or chair back section 3l, and a foot or leg `section32 which is narrower than the head section 3l. The head section 3l isslightly narrower than the middle Section 3u, as clearly illustrated inFigure 10. The outer end of the head section 3l of the mattress unit isprovided with a suitable hem at 33, leaving an end loop 34 for removablyreceiving a head dowel rod or bar 35, the ends of which project beyondthe sides of the loop 34 for engagement in side frame members, ashereinafter .more fully described. The outer end of the mattress rootsection 32 is also provided with a hem 33, forming a loop portion 34 forremovably receiving a foot dowel rod or bar 3E, the ends oi whichproject for engagement in the side frame members, as hereinafter morefully described.

Disposed longitudinally along each of the side margins of the mattressstrip are side frame units, each comprising an intermediate rail 31constructed of wood or other suitable material, the outer side of whichis provided with a lon- `gitudinal groove 33 (Figure 3) for thereception of a clamping strip 39 for securely holding the side margin ofthe mattress center section 3u clamped in the groove 38. The clampingstrip 3e is held in position by means of screws fit1 or other suitabledevices. For the purpose of mounting the mattress unit upon the basesupporting unit ofthe device, each of the intermediate side irame railmembers 31 has engaged in the lower surface at each end thereof anattaching bolt 4i having a washer 42 engaged thereon. Secured on theinner side of the head end of each of theframe rails 31 is a stop orspacing block Pivoted to the head end of each of the side frameintermediate rails 31, by means of a wing bolt 44, is the inner end ofaside frame head rail 45 provided with a dowel receiving opening 46 nearthe outer end` of the inner side thereof. l i

Pvotally supported on the outer surface near `one end of each of thehead side rails 45 `is the upper end of a. head leg 41 constructed ofmetal or other suitable material. Rigidly secured on the outer surfaceof each of the head rails 45, near one end and adjacent the lower edgeof the head rail, is a sto-p member or block 48 for limiting the swingof the leg 41 when the same is swung downwardly to a supporting positionfor use, as illustrated in Figures l. and 2, To prevent accidentalcollapsing of the legs 41, a

`spring-controlled stud or pin 49 (Figure 12) is` mounted in the headrail 45 to project from the inner side thereof to engage the side of. aleg 41 opposite the stop block 43. To swing the leg 41 into a closedposition adjacent the head rail 45, it is only necessary to depress thespring-controlled pin 49.

Rigidly secured to the inner face of the `foot end of each oi theintermediate side frame rails 31 is a spacing block 5t. Pivotallysupported on the spacing block 5u, by means of a wing bolt 5l, is theinner end of a side frame foot rail 52 constructed of wood or othersuitable material. The inner face of the outer end of the side framefoot rail 52 is provided with a recess or opening 53 for removablyreceiving one end ofA the foot dowel bar Zit. Pivotally supported at oneend on the inner side of each of the frame ioot rails 52 is `one end ofa foot leg 54, the swing of which is limited by means of a stop block orstop nut 55. To prevent accidental collapsing of the foot leg 54, eachoi the foot rail frame members 52 is provided with a spring controlleddetent or pin 49 similar in construction to that illustrated in Figure12.

For the purpose of securing the side margins of the head and footmattress sections 3| and 32 respectively to the respective side framehead rails 45 and foot rails 52, the side margins of the mattressrheadand foot sections are provided with oval fastener eyelets 5G for theremovable reception of oval curtain fasteners 51 secured upon the topsurfaces of the side frame rails 45 and 52, as illustrated in Figure 9.

Whenthe combination bed and chairis not in use,the base section isadapted to be collapsed, as illustrated in Figure 4, and the bed ormattress section is adapted to be collapsed, as illustrated in Figure 8,so that both of the collapsed sections maybe placed side by side withina suitcase section 2, as illustrated in Figure 2. The opposite half ofthe suitcase, namely, the Section l is adapted to have removably engagedtherein a folding and collapsing chair 58 of the type illustrated in myco-pending application for patent entitled Chain iiled of even dateherewith, Serial No. 238,99'1.- Several of the collapsed chairs 58 maybe carried in the suitcase section i, if desired.

From the assemblage illustrated in Figure 2, it will be noted that aconvenient furniture combinationV is provided in the collapsiblesectional combination bed and chair and the collapsible and folding typeoi chairs which may be conveniently stored and transported in acombination suitcase and table to provide a very convenient camping orbeach outt.

To set up the combination bed and chair into the assembled relationshipready for use, as illustrated in Figure l, the base unit, illustrated incollapsed form in Figure 4, is iirst opened up by dropping the legs I1into a vertical position and projecting the latch bolts i8 from thedotted line position illustrated in Figure 6 into the full line positionto prevent the base legs from accidentally collapsing. The side rails 4are now separated, thereby opening up the transverse hingedly connectedbrace rails 22 and simultaneously stretching the brace straps 29. Withthe brace rails 22 in extended position, as illustrated in Figure 5, thelatch bolts 25 fall into position by the action of gravity, asillustrated in Figure 7, to prevent accidental collapsing of thehingedly connected trans'- verse brace rails 22.

The collapsed mattress or top section is now partly opened up and placedupon the base section by engaging the attaching bolts ll and the washerd2 in the T-slots I3 and top slots I4 provided in the metal cornercastings of the base section. With the middle portion of the top ormattress unit engaged to the base unit, the mattress side frame, headrails i5 and foot rails 52 are swung outwardly from the full linepositions illustrated in Figure 9 into the dotted line positions, andthe end legs 4l and 52 are swung downwardly into the full line positionsillustrated in Figure 1 to complete the opening up of the mattress framesection. The mattress end sections 3l and 32 are now opened up and thedowel rod 35 is engaged to the loop portion Sli of the mattress headsection 3i, while the dowel bar 36 is engaged to the loop portion 34 ofthe mattress foot section 32. The ends of the dowels are engaged in therecesses provided in the side frame rails 45 and 52, therebytransversely stretching the mattress strip within the set up mattressframe. rIl'le bed is now in a position for use, as illustrated in fulllines in Figure 1.

For the purpose of converting the bed sections into a camp or deck chairor the like, it is only necessary to swing the head section upwardlyinto the dotted line position shown in Figure 1, allowing the headsection legs 4l to have the lower ends thereof engaged behind a stopbead or flange 59 integrally formed on the top of each of the frontcorner castings', as illustrated in Figure 3. rIAhe head legs iltherefore act as braces to hold the front section in an inclinedposition to serve as the back of a chair. The foot section is now swungdownwardly from the full line position illustrated in Figure 1 into thedotted line position to provide a leg rest. The intermediate section 3Dof the mattress strip now serves as the seat portion of the chairconstruction.

It will, of course, be understood that many details of construction maybe varied through a wide range without departing from the principles ofthe invention, and it is therefore not the purpose to limit the patentgranted hereon otherwise than necessitated by the scope of the appendedclaims.
